1What is heredity? What carries hereditary characters from parents to offspring?
2Define genetics. Name two of its sub-branches.
3List the seven pairs of contrasting characters Mendel studied in the pea plant, with the dominant form first.
4Why did Mendel select the pea plant for his research? Give any four reasons.
5Describe Mendel's experiment with pure tall and pure dwarf pea plants up to the F2 generation.
6What did Mendel find when he self-pollinated the different F2 plants to get the F3 generation?
7Differentiate between phenotypic character and genotypic character. Write both ratios for the F2 generation of Mendel's tall and dwarf experiment.
8What is the difference between a monohybrid cross and a dihybrid cross? Give an example of each.
9State Mendel's law of dominance and explain it using guinea pigs.
10State the law of purity of gametes. Explain it with the self-pollination of F1 hybrid pea plants.
11The dwarf character does not appear at all in F1, yet it reappears in F2. Explain why.
12Two tall pea plants are crossed and some of their offspring are dwarf. What must the genotypes of the two parents be? Give a reason.
